The Cobb 3-Port Boost Control Solenoid (BCS) is a critical upgrade for enthusiasts looking to maintain precise boost pressure and improve turbocharger response. Unlike the factory bleed-style solenoid, this 3-port unit uses interrupt-style logic to provide much faster spool-up and more stable boost targets across the powerband. This unit is specifically engineered to handle the higher boost levels common in modified EJ-series engines where the OEM component often fails to maintain consistency.

  • Direct bolt-on installation using factory mounting points
  • Plugs directly into the OEM electrical harness for a clean, plug-and-play setup
  • Interrupt-style 3-port design for superior wastegate control
  • Constructed for durability and high-heat resistance in the engine bay
  • Manufacturer Part Number: 712750

Note: Proper ECU calibration (tuning) is required immediately after installation to ensure the vehicle operates safely and effectively with the new boost control logic.
